bescenoe, with the base of the antennae, front of head, and the anterior legs, except 

 more or less of upper margin, yellow or reddish-yellow ; the whole of the coxae are 

 often more or less ferruginous ; head very finely punctured, antennae rather long, 

 with joints 6 — 10 gradually increasing in length and not moniliforrn ; thorax not 

 much broader than long, narrowed in front, with the posterior angles almost right 

 angles, sculpture very fine ; elytra transversely strigose, the sculpture being distinct, 

 but finer than in the allied species, and much stronger than that of thorax ; tibial 

 spurs testaceous. Length, 2| — 4 mm. 



Male with the antennae longer than in female, the anterior tarsi with the first 

 joint, transverse, slightly dilated, and the second and third joints oblong, strongly 

 dilated ; the third ventral segment of the abdomen is narrowly emarginate in the 

 middle, and is furnished with two narrow laciniae or appendages, which are approxi- 

 mate at base, and gradually diverge and curve inwards towards each other at apex ; 

 these appendages almost reach the apex of the abdomen. 



Female with the antennae slightly thickened towards apex, abdomen simple. 



On flowers of whitethorn, by sweeping among grass, &c. ; common 

 and generally distributed throughout the kingdom. 



The yellow colour of the front of the head is variable, extending 

 sometimes over a greater and sometimes over a lesser extent of surface ; 

 a variety occurs on the continent (A. lateralis, F., nee Thorns.), in 

 which the yellow colour extends to the front and sides of thorax ; I 

 have not, however, seen any British examples. 



A. Garnetsi, n. sp. 



In size, shape and general appearance closely resembling A. frontalis, from 

 which it maybe known by the somewhat longer and more slender antennae and more 

 evident sculpture, which is intermediate between that of A. frontalis and A. rtifi- 

 labris ; the legs also are differently coloured, the anterior pair being pale yellow, 

 with the exception of the apex of the femora, which is dusky above ; the intermediate 

 and posterior femora are also entirely, or almost entirely, yellow, the tibiae being 

 more or less variegated, and the tarsi fuscous ; the antennae are long and slender, 

 with the joints much longer than broad ; the thorax is scarcely broader at base than 

 its length from base to apex ; the chief difference, however, lies in the male charac- 

 ters ; in this sex the third segment is much elongated, and is furnished with two 

 rather stout and widely separated appendages, which are strongly curved inwards 

 towards one another, and enclose between them an almost circular, smooth and 

 shining space ; their appendages reach quite to the apex or extend a little beyond it ; 

 the anterior tarsi are not strongly dilated. Length, 2f — 3£ mm. 



On flowers, &c. ; taken in some numbers by Dr. Power at Ditton, 

 Horsell, Cowley and Claygate (Esher), and set aside by him as a new 

 species, but never, apparently described. As, however, there is already 

 a Mordellistena variegata, F., I have, in order to avoid confusion, 

 adopted a new name, and called it after the late Mr. W. Garneys, a 

 mutual friend of Dr. Power and myself, to whom I owe the fact that 

 I ever studied Coleoptera at all.
